School Refusal Medical Letters: What a GP Letter Can and Cannot Do

Parents dealing with school refusal almost always arrive at the same question: "Can I get a letter from my GP to exempt my child from school?" The answer is more complicated than most expect — and misunderstanding it is one of the most common ways families end up facing fines.

What a GP Letter Actually Does

A general practitioner or primary care physician can write a letter confirming that your child has a medical condition — anxiety, depression, panic disorder — and that they are currently unfit to attend school. This letter serves as clinical evidence. It does not serve as a legal exemption.

The distinction matters. In England, the authority to authorise or unauthorise an absence rests entirely with the headteacher. A GP letter supports the case for authorising the absence under illness codes, but the headteacher is not legally required to accept it. If the school considers the note too vague or insufficient, it retains the right to mark absences as unauthorised (Code O) — and those absences count toward the penalty notice threshold.

DfE statutory guidance does advise schools against routinely demanding formal medical evidence for every mental health-related absence, recognising that GP services are overburdened. But individual schools interpret this guidance with wide variation.

Why Vague Letters Fail

The most common GP letter says something like: "I can confirm that [child] suffers from anxiety and is currently unfit to attend school. I recommend a period of rest at home."

This fails on two fronts. Legally, it does not specify a diagnosis, does not identify the specific harm attending school would cause, and does not recommend concrete educational adjustments. Practically, it gives the school no actionable information about what would need to change for the child to return — leaving attendance officers to treat the absence as temporary and open-ended.

What Makes a Medical Letter Effective

A letter from a specialist — a child psychiatrist, clinical psychologist, or CAMHS consultant — carries substantially more legal weight. The most effective letters include three elements:

1. A specific clinical diagnosis — not "anxiety" alone, but the clinical picture: generalised anxiety disorder, school-specific phobia, autistic burnout, PTSD from school-based bullying
2. A statement that attending the school building currently poses a risk of psychological harm — this is the language that engages statutory duties
3. Specific recommendations for educational adjustments — Section 19 alternative provision, homebound instruction, reduced timetable, or formal withdrawal

When the letter contains these elements, it triggers different obligations. In England, a specialist report confirming a child is medically unfit for mainstream school obligates the local authority under Section 19 of the Education Act 1996 to arrange suitable alternative education. In the US, clinical documentation supports 504 accommodation plans or IEP modifications for homebound placement.

The Hierarchy of Clinical Evidence

Not all medical documents carry equal weight:

GP letter — supports temporary illness absence; limited legal authority. Schools may accept it for short periods but will push for school return if it continues.

Specialist clinical report (psychiatrist, clinical psychologist, paediatrician) — triggers statutory duties for alternative provision; strongest evidence in penalty notice challenges and prosecutions.

Formal statutory exemption — exists only in specific jurisdictions. In New Zealand, a Certificate of Exemption under Section 38 of the Education and Training Act 2020 legally supersedes compulsory attendance. In Ireland, registration on the Tusla Section 14 register provides formal legal exemption.

How to Get the Right Documentation

If your child is experiencing severe school refusal:

Start with your GP. Request a referral to CAMHS (UK), a child psychiatrist, or a clinical psychologist. Make clear that you need a specialist assessment, not just a repeat prescription or a "wait and see" recommendation.

If CAMHS wait times are prohibitive (12–36 months is common in England), consider a private assessment. A private clinical psychologist's specialist report can provide evidence for a Section 19 request; the legal effect depends on the report's findings and the applicable education rules.

When speaking to the clinician, be specific about what you need the letter to address: the diagnosis, the risk of harm from continued school attendance, and recommendations for educational provision. Clinicians are not naturally trained to write letters that engage statutory education duties — most need guidance on what legal thresholds the letter must meet.

Keep copies of everything. Every clinical letter, every email to the school forwarding the letter, every response from the attendance officer. If your case reaches a penalty notice challenge or magistrates' court, your documented trail of seeking and providing clinical evidence is your primary defence under Section 444(2A).
